Why might a limit order show a price-protection warning or be rejected?
Before submission, a limit order is checked against the page's price-protection and input-validation rules, designed to prevent unnecessary losses from input errors. Common rules include:
- Normal resting orders are unaffected: when going long, the limit price can be below the current best ask; when going short, it can be above the current best bid — these orders simply rest as pending orders and are not rejected solely for that price relationship;
- Deviation warning: when the limit price deviates from the reference price by more than roughly 3% (subject to the live page), the system shows a warning prompt requiring confirmation before submission — orders with an excessive deviation in the risky direction (e.g., a buy priced far above market) may be rejected outright;
- Other common rejection causes include insufficient account balance or a slippage setting that's too tight.
The exact reference price and final outcome are subject to what's shown on the live page and the system's actual settlement. If the issue persists after checking your balance and order parameters, please contact support via an in-platform ticket with your order ID so the technical team can investigate.
